I really don't want to lie down and win

When the pointer came to 08:30,

The originally noisy classroom suddenly fell into a state of silence.

Everyone watched Xu Mang walk in, without any books in his hand, and with a little expectation in confusion. When Xu Mang came to the podium, that invisible majesty rushed over his face.

"Cough cough!"

"Welcome everyone to my class, not to mention... I am a little nervous to come back here after a long absence." Xu Mang said with a smile, "I was so nervous that I forgot to bring my books... "

"..."

"..."

"..."

The atmosphere was still serious at first, but when Xu Mang spoke... he became extremely light-hearted. Just like the legendary Xu Mang, he was very approachable.

"All right!"

"Don't waste everyone's time." Xu Mang put away his playful mood, picked up chalk on the blackboard behind him, and wrote a few words Majorana neutrinos.

"This I think..."

"Everyone should know, right?" Xu Mang tapped on the blackboard behind him, and asked calmly, "An antiparticle is its own fermion."

Those present are all high-achieving students.

It is natural to know this so-called Majorana neutrino, but the Majorana neutrino is not yet clear, and the road ahead is very dark, almost all scientists in the world think so.

"You guys are lucky today!"

"I will narrow down the search range for Majorana neutrinos within three hours!" Xu Mang smiled, his words revealing incomparable confidence.

As soon as the voice fell,

There was an uproar!

......

The first thousand and 150 chapters three, this is the key to unlock the secret

Hearing Xu Mang's words, there were bursts of exclamations at the scene, and the atmosphere at this moment was instantly ignited. Everyone's eyes were fixed on Xu Mang, with a little trepidation and a little expectation. Could it be... Want to witness history?

If academician Xu can narrow down the scope of the Majorana neutrino search, then there is a chance to surpass the existing particle physics and become one of the major breakthroughs in modern physics. Of course... this is only at the most ideal stage After all, Academician Xu said just now...he will spend three hours explaining this issue.

Three hours...

Since Ettore Majorana published his hypothesis on the existence of this particle 90 years ago, there has been no evidence to prove the existence of this particle, and now many people think that this hypothetical particle for more than 90 years should no longer exist, because It is difficult for everyone to determine a range.

result...

Academician Xu suddenly said...he has this ability, to be honest...If the person standing opposite was not Academician Xu, just relying on what he said just now, this kind of arrogant self-confidence will definitely be given to him in minutes Education, but he is Xu Mang!

The greatest physicist in the world at present, the god of contemporary physics... It's not worth the name, he said that he can narrow the search range of Majorana neutrinos, then it will definitely be narrowed, there is no suspense!

"Fuck..."

"I said why the left eyelid keeps twitching today. It turns out that today we can witness the birth of a miracle!" He Weijie's companion said with horror at the moment: "Weijie...what do you have to do with this Majorana neutrino? Thoughts? Although this is the field of high-energy particles, I remember that you participated in a scientific research project on high-energy particles."

He Weijie didn't speak for a long time when he heard his companion's words... After a long silence, he said seriously: "I don't know what to say... There is no known Majorana fermion among the current elementary particles, and now There is still a lack of understanding of the nature of neutrinos, unless academician Xu has a way to solve double beta decay."

"is it?"

"How difficult is this?" He Weijie's companion asked curiously.

"How should I put it..." He Weijie frowned, and said seriously: "Because once the experiment proves that neutrinoless double-beta decay does exist, it will make a big step forward in people's understanding of the nature of neutrinos. A little...you should know how difficult it is!"

hiss!

So scary!

The eyes of He Weijie's companion changed, becoming a little excited and eager, and said: "Then... then if Academician Xu provides a solution today, this... This is basically Academician Xu invincible... an unprecedented triple promise There must be no suspense about the Bell Prize in Physics!"

"Ha ha..."

"Let's see again..." He Weijie smiled wryly. In fact, even if Academician Xu did not solve the neutrino double-beta decay problem, he could still win this year's Nobel Prize in Physics. The previous big discoveries changed the whole world. The structure of the physical world.

"Speaking of which, don't get too excited... This problem is really difficult. In fact, I don't believe that Academician Xu can solve this problem." He Weijie said seriously: "It's really too difficult. Reservations."

"Really?" He Weijie's companion thought for a while and said helplessly, "Maybe..."

"real..."

"First of all, neutrinos are uncharged particles produced by neutrons through beta decay, and interact with other particles through weak forces." He Weijie said seriously: "Although there are now experimental evidences that there are three types of neutrinos, and The masses vary, but their individual masses are currently determined."

"Neutrino double beta decay is a special case of the ordinary nuclear beta decay process...In this process, neutrons in unstable atomic nuclei emit electrons and antineutrinos and become protons." Weijie He said: "When the nucleus When the decay process does not proceed by way of single beta decay, double beta decay is emitted."

"to be honest..."

"Double beta decay is actually two single beta decays, but there is no ability to observe the intermediate state of the two single beta decays." He Weijie said: "This is really too difficult...others can't solve it after a lifetime of research."

That's someone else!

But Academician Xu is not a human being!He is God!

He Weijie's companion said: "Don't be so pessimistic. If Academician Xu really solves it... We will be the world leader in this field in the future. With the large collider under construction, the advantage is too great... "

At this time,

Xu Mang turned around suddenly and wrote a formula on the blackboard. This formula seemed familiar... but he couldn't remember where he had seen it before. This caused great doubts to all the students present. Familiar...but can't remember at all.

"what?"

"What is this?" He Weijie's companion asked in confusion, "Weijie...do you understand?"

"..."

"I don't understand." He Weijie shook his head, frowned and said: "This may be a company, or it may be a formula, forget it... let's not study it, wait for Academician Xu to explain himself, what now? It's useless to even think about it."

"Ok!"

moment,

There is a lot of new content on the blackboard. At first, everyone can understand the rest of the content except for the formula that they don’t know at all, but as time goes by, the following content is basically not understood. .

now,

He Weijie's friend's expression gradually became a little confused. He secretly glanced at his pelvis and found that He Weijie was also a little confused, so he asked cautiously: "It's over...I...I seem to be starting to not understand Academician Xu What are you writing?"
